Abstract

The invention provides a heterogeneous master-slave teleoperation control method and device based on force guidance. The method and device consider that the current position tracking between a masterarm and a slave arm is easily affected by a system signal when the position tracking is realized through position control, and when the system signal is discontinuous, the smoothness of the teleoperation is significantly affected, and the slave arm is damaged in severe cases. Therefore, in the master-slave teleoperation control process, a slave arm target position is generated according to masterarm end position information and slave arm end position information in a preset period, the slave arm target position is compared with a slave arm real-time position to determine a position error between the master arm and the slave arm, and then the position error is converted into a virtual elastic tension to realize the transformation from the position tracking to the force control. Moreover, since the discontinuity of the force only causes acceleration jumps and slow changes in speed, the motion of the slave arm is always continuous and smooth, and the damage to the slave arm is not caused.

Description

technical field [0001] The invention relates to the technical field of teleoperation robots, in particular to a force-guided heterogeneous master-slave teleoperation control method, device, storage medium and operating robot. Background technique [0002] At present, the maintenance work of power distribution overhead lines is gradually replaced by special operation robot equipment. Compared with manual maintenance, it has the advantages of low safety risk and high operation efficiency. [0003] The existing master-slave teleoperation control of special operation robots is all based on pose mapping. For isomorphic master-slave control, the master arm sends angle signals of each joint to the controller, and the controller controls the angle movement of each joint of the slave arm to track the signal of the master arm to realize teleoperation; for heterogeneous master-slave control, the master arm sends For the terminal pose signal, the controller uses inverse kinematics to s...
